Detailed description of the invention
For being more fully understood that the present invention, with detailed description of the invention, embodiments of the invention are described further below in conjunction with the accompanying drawings, see Fig. 1 to Fig. 3:
Automatic detection device according to embodiments of the present invention, its Cleaning Principle: after shaft sleeve workpiece to be measured is sealed, inner inflatable toward workpiece, flawless certified products are air tight, air pressure inside is stable, very nearly the same with external air source output pressure, has crack defective work, when air pressure to certain numerical value can leak gas, so air pressure is unstable or voltage stabilizing numerical value is less.Digital electronic air gauge gathers pressure information, and can set unlatching air pressure according to experimental data, and when air pressure reaches to set air pressure, air gauge output Continuity signal, experiment shows, crannied workpiece air pressure is below 0.45MPa.
In order to realize above-mentioned testing goal, the present embodiment include be connected on support feed mechanism, location sealing mechanism, air tightness detection machine structure.Feed mechanism is made up of vibrosieve, Timing Belt connecting gear, and the discharging slide rail end of vibrosieve is concordant with belt one end of belt transmission agency, and the other end of belt arranges location sealing mechanism.In order to ensure Timing Belt tensile force to bear workpiece weight, simultaneously the most again can fast and easy dismounting, step band wheel seat holds out against after screw holds out against by upper use, is fixed on support.
Location sealing mechanism by pushing cylinder, V-type pushing block, block, sealing gasket, compression cylinder, plug form, the front end of V-type pushing block is V-shape, can self-centering, thus be accurately positioned.V-type pushing block is connected to push cylinder cylinder rod end, in order to push exactly, pushes cylinder and selects TN10 × 100 double-rod cylinder.The axle sleeve to be measured that belt is sent by V-type pushing block under the driving pushing cylinder is pushed into block.Being provided with the sealing gasket of closure rotating ring stationary ring bottom face below block, belt, sealing gasket all keep concordant with platform, it is ensured that it is smooth and easy that rotating ring stationary ring workpiece for measurement moves middle held stationary.Block upper vertical is provided with compression cylinder, and compression cylinder cylinder rod is connected to block the plug of workpiece for measurement upper surface, and compression cylinder promotes lower end cap to be sealed workpiece upper surface.Compression cylinder need to provide bigger pressure, and cylinder diameter is relatively big, and mobile exactly of wanting, the present embodiment compression cylinder selection TN25 × 25 double-rod cylinder.
Air tightness detection machine structure includes pneumatic head, and pneumatic head runs through plug, connects with workpiece lumen, and loading line connects digital electronic air gauge.It is provided with blanking mechanism for sorting, including blanking cylinder, blanking port and sorter assemblies along block side.Blanking cylinder be arranged on block length direction side, blanking port is arranged on the opposite side of block.When, after compression cylinder and pushing cylinder homing, the promotion of blanking, workpiece detection completed falls from blanking port.In order to sort non-defective unit and have the defective products of crackle, blanking port position connects sorter assemblies.The sorter assemblies of the present embodiment has two ways, and sorter assemblies mode one is for being provided with chevron shaped slideway, and a passage is non-defective unit passage, and another passage is defective products passage, and the crotch at chevron shaped slideway is provided with sorting cylinder.Sorting cylinder end is connected with plectrum, when testing result is defective products, and plectrum closure non-defective unit passage, the defective products having crackle falls into defective products from defective products passage and collects frame, when testing result is non-defective unit, plectrum closure defective products passage, non-defective unit workpiece falls into non-defective unit from non-defective unit passage and collects frame.The mode two of sorter assemblies, for being provided with defective products splicing slide rail in blanking port position, connects splicing cylinder bottom splicing slide rail, if workpiece sensing is defective products, splicing cylinder promotes, and splicing slide rail moves catches, above blanking port, the defective products workpiece pushed through.If workpiece sensing is non-defective unit, splicing cylinder is failure to actuate, and non-defective unit falls from blanking port.
In order to realize automatization, reduce human input, detecting equipment configuration electric control system in the present embodiment, electric control system controls to push cylinder, compression cylinder, sorting cylinder action, by the electric machine rotation of driver control Timing Belt connecting gear, the vibration of vibrosieve by electromagnetic valve.The extreme position of each cylinder arranges sensor and cylinder carries out feedback control, and V-type pushing block position belt is provided above proximity switch, is used for triggering signal, controls to push cylinder action.Receive the barometric signal of digital electronic and judge the air-tightness of workpiece.
Implementation process of the present invention is: open machine, press and release the button, shaker vibration discharging, dynamic and static ring work openings slides to Timing Belt from vibrosieve slide rail facing downward, Timing Belt motor starts to rotate, and drives Timing Belt, and workpiece starts to transmit, when workpiece is below proximity switch, Timing Belt motor stalls.Pushing cylinder solenoid valve and obtain electric, push cylinder action, workpiece is pushed at block by V-type pushing block, and workpiece upper end surface is immediately below plug, and lower surface is in above rubber blanket.Compression cylinder action, plug workpiece pressing upper surface, lower surface is by rubber seal.The pneumatic head measured workpiece inner chamber inflation being arranged in plug, inflated to inside workpiece in the unit interval, if workpiece flawless is air tight, and digital air gauge numerical stability, exceed the force value of setting, export a Continuity signal.The defective work then air pressure having crackle declines substantially, will not trigger signal.After judging whether to have crackle, compression cylinder and the pushing equal dead electricity of cylinder solenoid valve, plug rises, and V-type pushing block returns in situ.Blanking cylinder solenoid valve obtains electric, releases workpiece.If using chevron shaped slideway, then sorting cylinder is used to drive plectrum to gate passage.If using splicing slide rail, then sort qualified workpiece with splicing cylinder and have crackle workpiece.After workpiece falls into rewinding frame, Timing Belt motor starts to rotate, and starts the detection of next workpiece, moves in circles, complete fully-automated synthesis.
